Power Lithium Battery Development History

The lithium-ion battery is a kind of secondary battery (rechargeable battery), which mainly depends on the movement of lithium ions between the positive electrode and the negative electrode to work. During the charge and discharge process, Li+ intercalates and deintercalates back and forth between the two electrodes (when charging, Li+ is deintercalated from the positive electrode and inserted into the negative electrode through the electrolyte. The negative electrode is in a lithium-rich state, and the opposite is true during discharge). Relative to traditional lead-acid batteries and nickel-chromium batteries, lithium-ion batteries have the advantages of high energy density, long cycle life, good charge and discharge performance, high voltage, no memory effect, less pollution, and high safety.

Lithium ion Battery

The current lithium-ion batteries for sale can normally be classified into consumer electronics battery, power lithium battery, and ESS lithium-ion battery according to their downstream applications. From the perspective of its development context, lithium-ion batteries were first importantly used in the 3C field, both consumer lithium-ion batteries. With the development of technology and the continuous improvement of battery performance, lithium-ion batteries are gradually being used to power electric tools, electric vehicles, and other transportation tools, namely, power lithium batteries. Since 2015, the development of the energy storage field has brought a new market demand for lithium-ion batteries. However, due to the low requirements for battery technology in the field of energy storage, the batteries used are important for the power lithium battery companies to eliminate surplus production or recycling of power lithium batteries.

From the perspective of market development speed, as the growth rate of the 3C industry market scale continued to decline after reaching its peak around 2010, the market gradually became saturated, and the growth rate of consumer lithium-ion batteries continued to decline. Although there was a slight rebound in 2017, the overall growth rate is still less than 10%. Since 2014, the rapid development of the global new energy automobile industry has caused the shipment of the lithium-ion battery industry to increase at a rapid rate of 27% per year in the past four years. As of the end of 2017, power lithium battery shipments reached 62.35GWh, accounting for 42% of lithium-ion battery shipments. In addition, from 2015 to 2017, energy storage batteries maintained a growth rate of about 40%, but still accounted for a small proportion of lithium-ion battery shipments.
